Answer 2

Resposta:

300

Explicação passo-a-passo:

$\begin{matrix}\space\space&2&0\\ \times \:&1&5\end{matrix}$

$\frac{\begin{matrix}\space\space&2&\textbf{0}\\ \times \:&1&\textbf{5}\end{matrix}}{\begin{matrix}\space\space&\space\space&0\end{matrix}}$

$\frac{\begin{matrix}\space\space&1&\space\space&\space\space\\ \space\space&\space\space&\textbf{2}&0\\ \times \:&\space\space&1&\textbf{5}\end{matrix}}{\begin{matrix}\space\space&\space\space&0&0\end{matrix}}$

$\frac{\begin{matrix}\space\space&1&\space\space&\space\space\\ \space\space&\space\space&2&0\\ \times \:&\space\space&1&5\end{matrix}}{\begin{matrix}\space\space&1&0&0\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&2&\textbf{0}\\ \space\space&\times \:&\textbf{1}&5\end{matrix}}{\begin{matrix}\space\space&1&0&0\\ \space\space&\space\space&0&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&\textbf{2}&0\\ \space\space&\times \:&\textbf{1}&5\end{matrix}}{\begin{matrix}\space\space&1&0&0\\ \space\space&2&0&\space\space\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&2&0\\ \space\space&\times \:&1&5\end{matrix}}{\begin{matrix}\space\space&1&0&0\\ \space\space&2&0&0\end{matrix}}$

~ ~ ~

$\begin{matrix}\space\space&1&0&0\\ +&2&0&0\end{matrix}$

$\frac{\begin{matrix}\space\space&1&0&\textbf{0}\\ +&2&0&\textbf{0}\end{matrix}}{\begin{matrix}\space\space&\space\space&\space\space&\textbf{0}\end{matrix}}$

$\frac{\begin{matrix}\space\space&1&\textbf{0}&0\\ +&2&\textbf{0}&0\end{matrix}}{\begin{matrix}\space\space&\space\space&\textbf{0}&0\end{matrix}}$

$\frac{\begin{matrix}\space\space&\textbf{1}&0&0\\ +&\textbf{2}&0&0\end{matrix}}{\begin{matrix}\space\space&\textbf{3}&0&0\end{matrix}}$

$=300$
